Dishwasher

ABSTRACT

Disclosed is a dishwasher capable of preventing distortion of a door. The dishwasher includes: a main body including a dish washing compartment having a dish entrance, and a door including an outer panel and an inner panel arranged with a space therebetween to open and close the dish entrance, the door including a panel-movement preventing member in the space between the outer panel and the inner panel to prevent relative movement between the outer panel and the inner panel. In the dishwasher according to the disclosure, the panel-movement preventing member is inserted in between the inner and outer panels of the door to prevent the relative movement between the inner and outer panels, thereby preventing the distortion into a diamond shape, strengthening a door structure, and preventing leakage due to the distortion.

TECHNICAL FIELD

The disclosure relates to a dishwasher, and more particularly to a door of a dishwasher, which has a panel-movement preventing structure for preventing distortion.

BACKGROUND ART

A door of a dishwasher is shaped like a box, of which an inner panel and an outer panel are coupled leaving a space therebetween by a side panel to accommodate various parts such as a control circuit board, wiring, etc. therein. In this case, the door is blocked in frontward, backward, leftward, rightward, and upward directions except a downward direction, and is hollow inside. In particular, the dishwasher mostly employs a lower hinged structure for opening and closing the door to be tilted up and down, and thus a load is focused on a lower portion when the door is opened and closed.

Such a door, which is hollow inside, in particular, shaped like a box opened downward, is deformed from a rectangular shape to a diamond shape, i.e. distorted because the inner and outer panels move relative to each other as the load of the door is focused on the lower portion when the door is opened to be tilted up and down.

In particular, the inner panel and the outer panel of the door need to be separated from each other to replace and repair internal parts. Thus, the inner panel and the outer panel are coupled to be detachable from each other. Such detachable coupling between the inner panel and the outer panel causes the distortion of the door due to the relative movement between the inner and outer panels.

Further, a door in a large-sized dishwasher has a large area, and is thus more vulnerable to the distortion caused by the relative movement between the inner and outer panels.

The distortion in the door of the dishwasher not only precludes the door from being smoothly opened and closed, but also causes water to leak during the operation of the dishwasher and consumers to be dissatisfied with durability.

BEST MODE

Below, embodiments of the disclosure will be described in detail with reference to accompanying drawings, to be easily carried out by a person having an ordinary skill in the art. The disclosure may be embodied in various different forms, and not limited to the embodiment set forth herein. For clarity of description, like numerals refer to like elements throughout.

Below, main operations of a dishwasher according to the disclosure and features of elements included in the dishwasher will be described in detail.

As shown in FIG. 1, a dishwasher 1 according to the disclosure includes a main body 100 internally formed with a washing compartment 110 opened frontward, and a door 130 mounted to the front of the main body 100 and tiltable up and down to open and close the washing compartment 110.

Inside the washing compartment 110, dish baskets 112 a and 112 b for accommodating dishes or the like are provided up and down. Further, to spray washing water toward the dishes accommodated in the dish baskets 112 a and 112 b, a stationary spray nozzle 113 a is provided in an inner upper portion of the washing compartment 110, and rotary spray nozzles 113 b and 113 c are respectively provided in middle and lower portions of the washing compartment 110. Further, a water supply pipe 115 with a water-supply control valve 114 is provided in the back of the washing compartment 110, so that washing water can be supplied to the inside of the washing compartment 110 at an initial stage.

Under the washing compartment 110, a washing pump 116 is provided to press and supply the washing water toward the spray nozzles 113 a, 113 b and 113 c inside the washing compartment 110. Further, a water collector 117 recessed at a predetermined depth to collect the washing water and sewage is formed in a lower portion of the washing compartment 110, and the water collector 117 is provided with a filter 118 to filter out cleaned sewage. An intake pipe 119 is connected between the washing pump 116 and the water collector 117 to circulate the washing water filtered through the filter 118, a drain pump 120 is provided under the water collector 117 to drain washing water after finishing a washing operation, and a drain pipe 121 is extended from the drain pump 120 toward the outside of the main body 100.

As shown in FIG. 4, the door 130 is coupled to opposite front lower sides of the main body 100 by one pair of hinge units 122. The one pair of hinge units 122 are respectively provided in the lower opposite sides of the door 130. As shown in FIG. 3, the hinge unit 122 includes a portion 124 a supported on a first lateral wall 135 a of an inner panel 132 of the door 130, a portion 124 b supported on a first coupling projection 135 b of the door 130, a portion 124 c supported on a support bracket 140, and a tilting lever 124 d bent and extended backward from the portion 124 c supported on the support bracket 140.

Further, a buffer spring 125 is provided in a lower inner portion of the main body 100 and allows the door 130 to be easily opened and closed. The buffer spring 125 connects a spring holder 126 provided in a lower inner portion of the main body 100 and the end of the tilting lever 124 d of the hinge unit 122. The buffer spring 125 prevents the door 130 from being suddenly opened when a user opens the door 130, and allows the door 130 to be easily closed with less force.

Further, as shown in FIG. 3, the door 130 is formed by an outer panel 131 and the inner panel 132 which are detachably coupled to each other. Although it is not illustrated in detail in the drawings, the front of the door 130 (i.e. the front of the outer panel) is provided with a control portion which includes a plurality of control buttons for controlling device operations, a display for displaying operation states, etc. Further, the door 130 is internally provided with wiring for electric connection with the control circuit board associated with the control portion on the front of the door 130.

The outer panel 131 and the inner panel 132 are separately provided and assembled into the door 130. The assembled door 130 includes a first lateral side 135 of the inner panel 132 and a second lateral side 136 of the outer panel. As shown in FIG. 3, the first lateral side 135 of the inner panel 132 includes the first lateral wall 135 a bent and extended backward from the left, right and upper edges of the inner panel 132, and a first coupling projection 135 b transversely bent and extended from the first lateral wall 135 a. The second lateral side 136 includes a second lateral wall 136 a bent and extended forward from the left, right and upper edges of the outer panel 131, and a second coupling projection 136 b transversely bent and extended again from the second lateral wall 136 a. The outer panel 131 and the inner panel 132 are coupled in a state that the first coupling projection 135 b and the second coupling projection 136 b are overlapped. The first coupling projection 135 b and the second coupling projection 136 b to be overlapped with each other include a plurality of screw holes 138 a and 138 b in corresponding portions to be fastened by screw and nuts. Of course, the door 130 may include the outer panel 131 and the inner panel 132 which are formed as a single body.

The inner panel 132 of the door 130 includes a recessed portion 137 positioned in a lower portion thereof and recessed toward the outer panel 131. The recessed portion 137 not only reinforces the structural strength of the door 130 but also used as a space expanded from the interior of the washing compartment 110. A space between the bottom of the recessed portion 137 and the outer panel 131 is narrow, but a space between an edge 139 surrounding the recessed portion 137 and the outer panel 131 is wide.

According to an embodiment of the disclosure, a panel-movement preventing member 200 is placed in a lower portion of the door 130. Further, the panel-movement preventing member 200 is placed including a middle portion of the door 130. The panel-movement preventing member 200 is interposed between the inner panel 132 and the outer panel 131 of the door 130. In particular, the panel-movement preventing member 200 is provided in a middle position of the edge 139 below the recessed portion 137 of the inner panel 132. The panel-movement preventing member 200 firmly holds and supports the inner sides of the inner panel 132 and the outer panel 131, and prevent the relative movement between the inner panel 132 and the outer panel 131. Effects on preventing the distortion of the door become better when the panel-movement preventing member 200 is extended from the lower middle portion of the door 130 in a transverse direction as long as possible. However, the wiring extended upward from the lower portion needs to be placed inside the door 130, and therefore the panel-movement preventing member 200 may have a length corresponding to one third of the transverse width of the door 130. Alternatively, the panel-movement preventing member 200 may be formed as long as possible and include a wiring through hole (not shown).

When the door 130 is distorted, the highest portion of the door 130, in which the control portion is positioned, is most affected by the distortion. Therefore, when a force of distorting the product is applied, the door 130 is easily distorted being deformed from a generally rectangular shape into a diamond shape. To solve this problem, it is effective to hold the middle portions of the inner panel 132 and the outer panel 131 assembled int the door 130 like an embodiment of the disclosure, rather than the opposite end portions (i.e. the hinge portions) of the door 130.

The panel-movement preventing member 200 may be provided as at least one panel holding block having surfaces which are in contact with and hold the inner surfaces of the outer panel 131 and the inner panel 132. Here, at least one panel holding block may be provided as a single body or an assembled body.

FIG. 5 is a cross-sectional view showing a mounted state of the panel-movement preventing member 200, FIG. 6 is a perspective view of the panel-movement preventing member 200 according to the first embodiment of the disclosure, and FIG. 7 is a partial cross-section view showing the mounted state of the panel-movement preventing member 200.

The panel-movement preventing member 200 includes an inner-side holding block 210 and an outer-side holding block 220 which are separately provided and assembled by concave and convex structures. Contact surfaces between the inner-side holding block 210 and the inner panel 132 and between the outer-side holding block 220 and the outer panel 131 may be properly set as necessary.

The panel-movement preventing member 200 may include the inner-side holding block 210 and the outer-side holding block 220 as shown in FIG. 6. The inner-side holding block 210 and the outer-side holding block 220 may be manufactured by plastic injection molding, but may alternatively be manufactured by a metal plate only or combination of the metal plate and the plastic.

The inner-side holding block 210 includes an inner panel supporter 212 supported on the inner panel 132, at least one concave portion 214 formed on the opposite side to the inner panel supporter 212, a tub avoider 216 concavely and transversely formed in a lower portion of the door, and a wiring holder 218 protruding at opposite sides.

The inner panel supporter 212 is attached to a lower middle inner surface (i.e. a convexly protruding portion) of the inner panel 132 by a screw or adhesive (or glue).

The at least one concave portion 214 receives and couples with a convex portion 224 of the outer-side holding block 220 (to be described later). The coupling between the inner-side holding block 210 and the outer-side holding block based on the concave and convex structures is needed to disassemble the inner panel 132 and the outer panel 131 to replace or repair the parts.

The wiring holder 218 is configured to arrange and hold the wiring extended upward from the lower portion inside the door 130. The wiring holder 218 includes first to third holding protrusions 217-1, 217-2 and 217-3 protruding from the opposite sides. The second and third holding protrusions 217-2 and 217-3 are spaced apart from each other in a transverse direction, and the first holding protrusion 217-1 is spaced apart from the middle between the second and third holding protrusions 217-2 and 217-3 in a direction perpendicular to the transverse direction. The first to third holding protrusions 217-1, 217-2 and 217-3 include wiring-accommodating grooves 219 on the surfaces facing each other to accommodate the wiring. The wiring is inserted and held in the wiring-receiving grooves 219 positioned in a space between the first to third holding protrusions 217-1, 217-2 and 217-3. The wiring holder 218 is not limited to the foregoing three holding protrusions, but may include two or more than four protrusions. Alternatively, the wiring holder 218 may be based on a wire directly compressing or binding the wiring with the spring and the like elastic body instead of fitting the wiring between the first to third holding protrusions 217-1, 217-2 and 217-3.

The tub avoider 216 refers to a groove for avoiding interference with a tub 128 protruding from the bottom of the washing compartment 110 when the door 130 is tiltably opened and closed. The tub 128 in the lower portion of the washing compartment 110 refers to a protrusion to prevent the washing water used in the washing process from leaking outside. The tub avoider 216 is lengthwise elongated in the lower portion of the inner-side holding block 210.

The outer-side holding block 220 includes an outer panel supporter 222 being in contact with and supported on the outer panel 131, and at least one convex portion 224 protruding from the side opposite to the outer panel supporter 222. The outer panel supporter 222 is attached to a lower middle inner surface of the outer panel 131 by a screw or adhesive (or glue). The at least one convex portion 224 is inserted in the at least one concave portion 214 of the inner-side holding block 210.

As described above, the panel-movement preventing member 200 connects and holds the inner surfaces of the inner panel 132 and the outer panel 131 to effectively reinforce the strength of the door 130, thereby maximizing convenience in use of the dishwasher, such as stable closure, prevention of leakage due to distortion, etc.

According to an alternative embodiment, the panel-movement preventing member 200 may be formed as a single body of the panel holding block, and have opposite surfaces facing the inner surfaces of the inner panel 132 and the outer panel 131, both of which are attached by adhesive. However, the continuous function of the panel-movement preventing member 200 is not expected when the product is repaired or unavoidably disassembled. Therefore, the panel-movement preventing member 200 may have a fastening structure, for example, a magnet, a hook, and the like easily detachable from one of the inner panel 132 and the outer panel 131.

FIG. 8 is a cross-sectional view showing that the panel-movement preventing member 300 according to a second embodiment of the disclosure is mounted to a door. The panel-movement preventing member 300 includes a middle holding block 310 placed in a lower middle portion of the door 130, and one pair of outer holding blocks 320 and 330 respectively placed in lower opposite sides of the door 130. The middle holding block 310 and the one pair of outer holding blocks 320 and 330 may be manufactured by plastic injection molding, but may be manufactured by a metal plate only or combination of the metal plate and the plastic.

The middle holding block 310 and the one pair of outer holding blocks 320 and 330 include inner panel supporters 312, 322 and 332 to be in surface-contact with the inner surface of the inner panel 132, outer panel supporters 314, 324 and 334 to be in surface-contact with the inner surface of the outer panel 131, and a tub avoider (not shown) formed on a bottom surface.

The one pair of outer holding blocks 320 and 330 includes inclined lateral surfaces 326 and 336 facing corners between the outer panel 131 and the second lateral wall 136 a. The inclined lateral surfaces 326 and 336 may include a lateral surface contact portion (not shown) extended being inclined toward the second lateral wall 136 a and being in surface-contact with the inner surface of the second lateral wall 136 a.

The outer panel supporters 314, 324 and 334 are attached to the inner surface of the outer panel 131 by adhesive (or glue). The inner panel supporters 312, 322 and 332 include permanent magnets 313, 323 and 333 detachably attached to the inner surface of the inner panel 132. In this case, the inner surface of the inner panel 132, to which the inner panel supporters 312, 322 and 332 are attached, include metal plates 311, 321 and 331 or magnets having opposite polarity. Instead of the permanent magnets 313, 323 and 333, one side between the inner panel supporters 312, 322 and 332 and the inner panel 132 may be provided with a hook, and the other side may be provided with a hook holder.

Each end portion of the inclined supporters 414 and 424 has a width gradually expanded and widened. The inclined supporters 414 and 424 having such wide end portions can effectively support the door 130 throughout a wide range in up and down directions. The inner panel supporters 412 and 422 are fastened to the inner surface of the inner panel 132 by adhesive (or glue). Alternatively, the inclined supporters 414 and 424 may keep only a contact state or may be detachably fastened. The one pair of inclined support holders 410 and 420 may include a single inclined support holder in which the inner panel supporters 412 and 422 are integrally connected to each other, instead of separate bodies supporting two spaced positions of the inner panel 132. The one pair of inclined support holders 410 and 420 may include at least one bending supporter (not shown) bent from the end portion of the inclined supporters 414 and 424 and being in surface contact with the outer panel 131 and/or the second lateral wall 136 a.

The dishwasher 1 may have the door 130, the width of which is narrow according to models. Thus, when the two separated supporters 615 and 617 are folded up to decrease in length, a space is decreased between the two positions supported by the inclined supporter 614 and 624 of the one pair of inclined support holders 610 and 620. Like this, change in length of the inclined support holders 610 and 620 allows the panel-movement preventing member 600 to be applicable in common to doors of products different in size, thereby reducing production costs.

FIG. 14 is a perspective view of a different inclined support holder 610. As shown therein, the inclined support holder 610 includes the bracket supporter 612 supported on one position of the support bracket 140; an inclined supporter 614 integrally extended from the bracket supporter 612 and inclinedly extended outward from the one position toward the corner between the outer panel 131 and the second lateral wall 136 a; and at least one bending supporter 616, 618 bent from the inclined supporter 614 and being in surface contact with the outer panel 131 and the second lateral wall 136 a. The bracket supporter 612 is fastened to the support bracket 140 by adhesive (or glue) or a screw. The end portion of the inclined supporter 614 is in contact with the corner between the outer panel 131 and the second lateral wall 136 a. The at least one bending supporter 616, 618 is in contact with the outer panel 131 and/or the second lateral wall 136 a. Here, the end portion of the inclined supporter 614 and/or the bending supporter 616, 618 may be in contact with or detachably fastened to the corner between the outer panel 131 and the second lateral wall 136 a, the outer panel 131, and the second lateral wall 136 a. As described above, the inclined support holder 610 can support all the corner between the outer panel 131 and the second lateral wall 136 a, the outer panel 131, and the second lateral wall 136 a.

FIG. 15 is a cross-sectional view schematically showing that a panel-movement preventing member 700 according to a sixth embodiment of the disclosure is mounted to the door 130. The panel-movement preventing member 700 includes the support bracket 140 for holding and supporting one pair of hinge units 122 separately placed in lower opposite sides of the door 130, one pair of inclined support holders 710 and 720 placed at opposite end portions of the support bracket 140, and an inner panel supporter 730 placed in the middle of the support bracket 140. When the support bracket 140 for holding and supporting the one pair of hinge units 122 is absent in the panel-movement preventing member 700, an additional support bracket for supporting the panel-movement preventing member 700 may be provided. The one pair of inclined support holders 710 and 720 may be manufactured by plastic injection molding, but may alternatively be manufactured by a metal plate only or combination of the metal plate and the plastic. The inner panel supporter 730 may be manufactured by a metal plate, but may alternatively be manufactured by plastic only or combination of the metal plate and the plastic. The support bracket 140 may be manufactured by a metal plate, but may alternatively be manufactured by plastic only or combination of the metal plate and the plastic.

The one pair of inclined support holders 710 and 720 has the same structure as the inclined support holder 610 of FIG. 11, and therefore repetitive descriptions will be omitted.

The inner panel supporter 730 is for example formed by bending and machining the opposite ends of the metal plate to have a ‘∫’-shaped cross-section, and has one bending side fastened to the middle of the support bracket 140 with a screw or adhesive (glue), and the other bending side fastened to the inner panel 132.
